"The most effective use of Bertin’s retinal variables are summarized in a visual format in the book Making Maps: A Visual Guide to Map Design for GISby John Krygier and Denis Wood. The chart below shows which visual variables, as they call them, are most effective for showing qualitative or quantitative differences according to Bertin. Krygier and Wood also show how to represent the attribute through points, lines, or areas.

Now that I’ve introduced all this, proceed with caution. Bertin’s visual variables, which often make sense, are based on his experience and intuition rather than hard core research. As in all cases, use your best judgment for making design decisions."
